The following illustration shows the dual inline memory module (DIMM)
2connectors and corresponding LEDs 1 on the system board.
Attention: Static electricity that is released to internal server components when
the server is powered-on might cause the server to stop, which might result in the
loss of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when working inside the server with the
power on.
To install a DIMM, complete the following steps:
1. Read the safety information that begins on page v and “Installation guidelines”
on page 7.
2. Turn off the server and peripheral devices, and disconnect the power cords and
all external cables.
3. Remove the side cover (see “Removing the side cover” on page 10).
4. Locate the DIMM connectors on the system board. Determine the connectors
into which you will install the DIMMs. Install the DIMMs in the sequence
shown in the following table.
